Three species of the gobiid fish genus Bryaninops were previously known for the Red Sea: B. natans, B. ridens, and B.yongei. Two new species are described, B. discus, similar to B. loki, differing in coloration and in having dish-like insteadof cup-like pelvic fins in adults; and B. spongicolus, closely related to B. dianneae from Fiji, distinct in having shorterpelvic fins, a rounded instead of truncate caudal fin, and differences in life color. Bryaninops loki and B. tigris are reportedas first records for the Red Sea, the former from a specimen from Sudan and an underwater photo from the Sinai Peninsula, the latter from an underwater photo taken off Egypt.
The infraorder Thalassinidea Latreille, 1831 [sensu stricto] includes three families: Thalassinidae Latreille, 1831; Upogebiidae Borradaile, 1903; and Laomediidae De Haan, 1849 (cf. Sakai & Sawada, 2006). However, recent examination of material from Kuwait in the Pershian Gulf, showed the occurence of a new species,Kuwaitupogebia nithyanandangen. et sp. nov., and this has made it possible to establish a new family, Kuwaitupogebiidae fam. nov., based on that new genus. The genusUpogebiaLeach, 1814 is known to include nine species from the Red Sea area, yet herein two new species,Upogebiaspongicolasp. nov. from the Reef at Hurghada, Red Sea, Egypt, andUpogebia jizanensissp. nov. from off Jizan, Saudi Arabia, Red Sea, can be added, based on material lodged in the collections of the museum in Frankfurt a. M.
This study is a revision of the poorly known genus Pseudochitinopoma Zibrowius, 1969 (Annelida, Serpulidae), erected for Hyalopomatopsis occidentalis Bush, 1905 from the West Coast of North America. Subsequently, an unnamed Pseudochitinopoma sp. nov. from the Seychelles (ten Hove 1994) (described herein as P. amirantensis sp. nov.) and P. pavimentata Nishi, 1999 were added to the genus. Ficopomatus capensis Day, 1961 is herein referred to Pseudochitinopoma, based on examination of the type material. Finally, Pseudochitinopoma beneliahuae sp. nov. was described from Western Australia and the Red Sea. Reproductive patterns and phylogenetic affinities of Pseudochitinopoma spp. are discussed.
Up to the present, 31 species of the infraorders Callianassidea Dana, 1852, and Thalassinidea Latreille, 1831 have been reported from the Red Sea area, of which nine, viz.,Gilvossius bouvieri(Nobili, 1904),G. gravieri(Nobili, 1905),G. maldivensis(Borradaile, 1904),Notiax amboinensis(De Man, 1888),Lepidophthalmus rosae(Nobili, 1904),Neocallichirus calmani(Nobili, 1904),N. indicus(De Man, 1905),N. vaugelasiDworschak, 2011, andPodocallichirus madagassus(Lenz & Richters, 1881), are reviewed in this paper for further unambiguous classification and identification. As a result of this review, one new genus,Lepidophthalminusgen. nov. and two new species,Gilvossius chichijimaensissp. nov. andNeocallichirus kenyaensissp. nov., are here proposed.
As part of a study dealing with polychaetes (Annelida: Polychaeta) from soft bottoms of the western coasts of AcapulcoBay, southern Mexican Pacific, 574 specimens of the genus Syllis Lamarck, 1818 were analyzed. Nine species are report-ed, of which Syllis garciai (Campoy, 1982) and Syllis glarearia (Westheide, 1974) are new records for the Mexican Pa-cific. Syllis magnipectinis (Storch, 1967), described from the Red Sea, is newly reported in the eastern Pacific; notes onits morphological variations and its distribution range are herein included. Additionally, two new species of Syllis are de-scribed: S. antoniae n. sp., is closely related to S. vivipara Krohn, 1869, but it has bidentate falcigers with a smaller sub-distal tooth and some falcigers with coarse spines on the edge. S. deleoni n. sp., is characterized by having bidentate falcigers with broad teeth and coarse spines and the body densely covered with papillae.
Two new species of the nudibranch genus Okenia Menke, 1830 (Goniodorididae) are described, one from eastern Australian waters and one from the western Indian Ocean. Okenia atkinsonorum sp. nov. is the third Australian species reported to feed on the bryozoan Pleurotoichus clathratus (Harmer, 1902) and is very similar in external shape and colour to the other two species, O. hallucigenia Rudman, 2004 and O. stellata Rudman, 2004. Okenia rhinorma sp. nov. is reported from Tanzania and the Red Sea. Its body shape and anatomy suggest it is related to the ascidian-feeding group in the genus characterised by O. aspersa (Alder & Hancock, 1845).
